To ett whom it may concern:

Ee it known that RICHARD J. WYNKoor, a citizen ofthe United States and resident of Bridgeport in the county of Fairfield State of (ionnecticut, has invented certain'new and useful improvements in hotographic--irinting Machines, of which the following is a specification.

object of, this invention is to pro-vide a photographic printing machine with an automatic paper feeding mechanism of such construction that by a singie operation the proper amount ci paper can be brought into position over the nefative und the same clamped properly in place. l

Other objects consist in the provision of means for .recording the printing operation and setting the recording device so that an alarm is sounded for signaling the operator when the desired number oi prints have been made. Still another object is to provide an arrangement whereby the lamps will be iliuminated at the proper time by the movement of the automatic paper feeding mechanism.

More specifically this invention consists in ijiroviding a light hor: construction for the reception of a negative and a negative retaining mechanism, and means for feeding the print paper into position on the negative, the paper feeding mechanism being adapted to operate the iliuminating means and when in normal position to engage and loci; the @ad over the print paper and negative. Mea-ns are also provided for regulating the movement or the paper feed infr mechanism to cause the proper amount of paper toy he drawn forward and arranged over the negative, which iatter may be of different sizes to better acornrnodate pictures or' different sizes.A l For the 'speoiicconstruction vand operation reference wiii be had to the accompanyng drawings forming a part of *this specification and whereinU like numerals `-of reference designate corresponding parts --throughont the several views, in which ""ig, l is a sido elevation of my complete hon.

are braced by the baseboard. Arra adjacent the table top l and between the legs? and 3 is the lightbox 5 in which may be located any suitable number of incandescent lamps 6. The top of this box is formed by the tabie top l and a portion of the top 'forming the top of the box is' cut away as at and is grooved for the reception of a transparent plate 8. This plate 8 forms the light transmitting opening through which the light penetrates for contact with the negative as will more clearly, hereinafter appear. 'Thev wall of the light 0 ening 7 is cut away as clearly shown in ig. to forni thevshoulder 9 for supporting the negative indicated by reference character 10. A removable plate ing therein is placed over the negative 10 to determine the sizeof the prints and may be substituted from time to time by other plates having larger or smaller openings for dierent size pictures. A clamping trarne l2 formed of thin sheet metal is hinged to swing on the pintle 13 which latter is supported by 'the members l1414.se cured to the side of the table top. The free end of this frame 12 is provided with hooks 15-15 formed integral thereto and projecting dowrm/ardly and inwardly for engagement with the rod 16 which is mounted similarly to the pintie 13 but on the opposite side of the'table. Another clamping frame i8 formed of a single piece of wire is mounted on the said pint-lc 13 and adapted to swing in substantially the same pla-ne as the said 4clamp 12. This latter clamp is also provided with a hook 19 for engagement with the rod 16.

For carryingthe paper which is usually in roll form I have provided a receptacle Z0 having a suitable hinged cover 2l. A slot 1s formed in this receptacle as shown at 22 by cutting away a portion of one of the edges of the cover 21 and through which the paper 23 is adapted to pass. In connection with this device there isalso arranged an indicator 24 and an alarm 25 for indicating and 1l having an opennotifying;r the operator ofr'the nuinber of' l roi registering mechanism within the box 24* 'which in turn operates the hammer 25L to strike the bell 25 when a certain number of prints are made. i

Arranged along the edges of one endvofv 'thereby in a .way to the table and extending approximately the 'light'opening are the guide members 2o and 27 under which the slide 45 of the aforesaid paper feeding` mechanism is adapted to travel. It will be seen that the guide member 27 is provided with aseries of notches 28 in which the stop 29 engages. This stop 29 is'loosely mounted and adapted tobe adjusted longitudinally on the'bar 30 t o engage the respective notches. Particular` attention is called to the fact that the end ot the stop member 29 projects through the.pa rticular notch in which itmay be seated and lnto the path of the feed slide 45 so as to be engaged limit the paper feeding movements.

The pad 31 may be of' conventional'construction and is resiliently connected to the operating member 32 by the springs 33. This member 32 which carries thepad is ot suitable rectangular form and may be ot Y any vdesired material, being provided with the handle 34' for convenient man" ulatipn. Pivotedannular side arms 35 and. ..Yliich form the supporting means for the member 32 extend along the` edge of said member and are secured thereto by screws 37. f These supporting bars are bent outwardlyftom y the edges of the operating member Sg'gfas indicated at reference numeral 38 to extend beyondzjtihe sides of the table and are then bent to `extend parallel. The pivot or hinge pointv is :formed at the apex of the angle formed by these bars 35 and `36 and thel pintles represented by the Vscrews 39 are mounted in the brackets 40, the latter being suitably secured to the table.

Curved links 41 and 42 connectI the ends,

tioned. -Upon each end of vthe transverse rocker shaft 43V are secured short arms 46 to which the links 41 and 42connect. These arms have flanges 46"*adapted 'for engagement With the outer edge of the-said links whereby the forward movement of the latter will cause an oscillatory movement of the said rocker shaft 43 and the' said'iixed arms 46. This oscillatory movement causes the gripping action of the engaging member 48 which' is secured to the transverse rocker shaft 43 by means of the screw 47. The face of this engaging member 48 vcan be serrated as shown and is adapted for clamping the paper against the upper face of the plate 45. Secured to the paper engaging member 48 is the catch 49 for engagement with the bolt 50 having a projecting finger piece carried by the member 32, which carries the pad.

The lawns G enclosed in the light hun are tion by the elevation of theadjustable memindicated a regulated amount of paper is in proper circuit with the switch whose plieb button is indicated at 51, This switch which normally is open is operated by engagement with the member 52 carried by the operating member. y

The operation of the device ,is as follows A supply of print paper being in the receptacle 20 in the form of a roll, one end is threaded through the opening formed;l therein at 22. The negative is then placed' in position on the shoulder 9 above the light transmitting opening and a mask plate ll placed thereon-'such as the type of negative may require, the latter being held in position by means of the hinged sheet metal clamping frame 12.. The end of the print paper above mentioned is now carried tor- Ward across the negative and is clamped. firmly place by means of the wire trame 18, the end of the paper extending sufficiently beyond the end of the negative to permitfthe engagement of the gripping member 48. Duringthese preparations the pad has necessarily been inv a raised 'posi ber which is now swung downwardly so that the pad is properly seated and in this low-v ered position it will be seen;v that the catch 49 engages and locks same firmly; The closin(c of this operating member'through contact with the push button 51 clbses the circuit and the lamps are properly illuminated.

After a proper time has elapsed the pad l and operating member are raised b first gripping the handle 34 drawing vthe bolt 50 and then lifting the operating member which by means of the connections shown causes thepaper gripping member 48 to swing downwardly to grip the paper against the plate 45. With the movement of this gripping member the entire paper mechanlsm moves along the tracks provided until the edge of the plate 45 engages the end of the adjustable stop 29 which projects' through one of the notches formed in lthe track 27. It will be obvious that this will accordingl carry the paper forward a predeterminel distance which is regulatedby the adjustment of the stop 29. By raising and .lowering the operating member as above ne ted into position over the negative and subjected to the light from the light box at each operation. When it is desired toprint from a new negative of a different size the Aproper amount of paper can be fed by changing the position of stop mentioned.

Various changes in the details of construction may be made without departing from the spirit of 'theinvention 0 What I claim as ,.new and useful and desire to secure byjLetters Patent, is:-
